We present an R = 45,000 Keck spectrum of the microlensed Galactic bulge G dwarf OGLE-2006-BLG-265, which has high (~60) signal-to-noise ratio despite its short (15 minute) exposure time, because the source was magnified by A ~ 135. While it is very metal-rich ([Fe/H] = 0.56), the higher temperature of this star compared with the luminous red giants usually measured in the bulge gives its spectrum many unblended atomic lines. We measure the abundances of 17 elements, including the first…

Clues to the Metallicity Distribution in the Galactic Bulge: Abundances in OGLE-2007-BLG-349S*
We present an abundance analysis based on high-dispersion and high signal-to-noise ratio Keck spectra of a very highly microlensed Galactic bulge dwarf, OGLE-2007-BLG-349S, with -->Teff ~ 5400 K. The
Chemical Composition of Faint (I ~ 21 mag) Microlensed Bulge Dwarf OGLE-2007-BLG-514S
We present a high-resolution spectrum of a microlensed G dwarf in the Galactic bulge with spectroscopic temperature T eff = 5600 ± 180 K. This I ~ 21 mag star was magnified by a factor ranging from
Measurements based on a large number of red giant stars suggest a broad metallicity distribution function (MDF) for the Galactic bulge, centered on [Fe/H] approximate to -0.1. However, recently, a
A High-Resolution Spectrum of the Highly Magnified Bulge G Dwarf MOA-2006-BLG-099S*
We analyze a high-resolution spectrum of a microlensed G dwarf in the Galactic bulge, acquired when the star was magnified by a factor of 110. We measure a spectroscopic temperature, derived from the
The metallicity distribution of bulge clump giants in Baade’s window
Aims. We seek to constrain the formation of the Galactic bulge by analysing the detailed chemical composition of a large sample of red clump stars in Baade’s window. These stars were selected to
Light, Alpha, and Fe-Peak Element Abundances in the Galactic Bulge
We present radial velocities and chemical abundances of O, Na, Mg, Al, Si, Ca, Cr, Fe, Co, Ni, and Cu for a sample of 156 red giant branch stars in two Galactic bulge fields centered near

Abstract The four main findings about the age and abundance structure of the Milky Way bulge based on microlensed dwarf and subgiant stars are: (1) a wide metallicity distribution with distinct peaks


The First Detailed Abundances for M Giants in Baade's Window from Infrared Spectroscopy
We report the first abundance analysis of 14 M giant stars in the Galactic bulge, based on R = 25,000 infrared spectroscopy (1.5-1.8 ?m) using NIRSPEC at the Keck telescope. Because some of the bulge
